For this project my group Jake, Jack and I we had to build a energy efficient car and our first idea for a more energy efficient car was a watered powered plastic container. Our goal was to make the car run five meters without having any human interference. The water idea didn't work so we had to change our whole car three days before it was due. The water powered car didn't work so we changed our idea to a spring powered care with scooter wheels. We had to work for three lunches in a row and make many tweaks, but we were able to get the car to go five meters all by itself.
Concepts:
Kinetic Energy: Kinetic energy is the energy the object has. It equals potential energy. You can find KE by half of the mass times velocity squared.
Thermal Energy: Thermal Energy is the part of total potential energy and kinetic energy of an object. To find Thermal energy you find how what the PE is and subtract the KE and the difference is the Thermal energy. This is because all the energy not transfered From PE to KE is made into heat, or Thermal energy.
Potential Energy: Potential energy is the amount of energy the object has in relation to height. You can find PE by mass times acceleration due to gravity times height.
Distance: Distance is how far something is from another thing. You can find distance by half of the acceleration due to gravity times time squared.
Acceleration: Acceleration is the change in velocity with respect to time. You can find acceleration by dividing force over mass.
Time: Time is measured in seconds and there are sixty seconds in a minute. We used time to show how fast our car went each meter.
I feel this project was much easier than I thought it was going to be. I thought it was going to be very difficult to get car go five meters without any human interference. We were able to do that only after we changed our idea. Overall I felt this project went really well although there were many peaks and pits. Throughout the project I also learned a lot about myself and gained new skills I can take with me to the next project. I learned how to be very patient when something is not consistent and to make a lot tiny adjustments instead of making on big one. For example, when we had to change our car to a spring powered car we made tiny adjustments over and over again to get it go consistently five meters. One thing my group did well was communicating and not getting overstressed about the deadline. When we stayed in at lunch for the last three days just to finish our car we were calm and didn't get made at each other. We also had some pits. One thing I will continue to improve upon is staying on task. Another thing I could of done better is saying all my ideas about the project that I come up with, even if they don't make sense right away.
